I've found my furever family!

He can be shy at first, but you can meet lovely dog friend once he adjusts to new environment. (This foster is his first home and it takes about a month to adjust perfectly.)
Loves to pet! Keeps asking for petting him. Easy to make him brushing teeth, ear cleaning, etc.
He feels easy for people to stay away on his meal time.
No food guarding. He can wait for his turn.
Not interested in toys.
Good with other dogs. Not playful but stay with other dogs peacefully.
No interest in cats on streets.
Now his foster doesn't have kids. But when he meets kids on streets, he tends to escape from that situation because most of kids make loud sounds and move quickly. He is not aggressive at all, so if they can wait for him, it would be okay to stay with kids.
House trained (inside and outside both, using pee pads at home)
When strangers come to home, he looks nervous, But accepting all touch from them.
Sometimes he has big interests in bins at home and makes it messy. We have to keep it from him.
He had separation anxiety at first but all trained well. He is smart and easy to train. Everything will be fine once he adjusts to new environment.
